Genes affected

GRWD1 (HGNC:21270): (glutamate rich WD repeat containing 1) This gene encodes a glutamate-rich protein that contains five WD-repeat motifs. The encoded protein may play a critical role in ribosome biogenesis and may also play a role in histone methylation through interactions with CUL4-DDB1 ubiquitin E3 ligase.

The c.545G>A (p.R182Q) alteration is located in exon 4 (coding exon 4) of the GRWD1 gene. This alteration results from a G to A substitution at nucleotide position 545, causing the arginine (R) at amino acid position 182 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
